Schneider Electric EGB34030 Molded Case Circuit Breaker

Schneider Electric EGB34030 is an E‑Frame molded‑case circuit breaker (MCCB) rated for 30 A in a three‑pole configuration for 480Y/277 VAC systems. It uses thermal‑magnetic trip protection and bolt‑on mounting, designed for straightforward installation in Square D NF panelboards. The official listing calls out an interrupting rating up to 65 kA at 480Y/277 VAC and notes the unit is TAA‑compliant, making it suitable for projects with government or other procurement requirements. As part of the EGB family, the 3P 30A device protects three‑phase distribution circuits and motors in commercial or light‑industrial equipment, providing short‑circuit and overload protection in panelboard applications. Within the same product line, variants such as EJB34030SARP exist, adding features like shunt‑trip and other options, which can entail different interrupt ratings and packaging. When selecting this breaker, confirm the exact SKU and rating with your Schneider Electric distributor to ensure the model matches your protection needs and electrical system voltage is 480Y/277 VAC. The EGB34030 is designed to fit standard E‑frame bolt‑on assemblies in compatible panelboards, delivering reliable trip performance while occupying a compact footprint relative to larger MCCB options.
